United States Patent 2,963,024 SMOKING FILTERS FOR CIGARS AND PIPES Sigmund Lichtstern and Herbert Lichtstern, both of 600 W. 161st St., New York, N.Y.

Filed Nov. 28, 1958, Ser. No. 776,827

3 Claims. (Cl. 131-10) The present invention relates to improvements in smokers articles and, more specifically, to filter arrangements for cigars and tobacco pipes, the term cigars whenever used hereinafter being intended to include cigarillios and other types of small rolls of tobaccos wrapped with tobacco and used for smoking, such as according to the act of July 24, 1897, c. 11, section 10, of the Revised Statutes of the United States, are classed as cigars.

One object of the present invention is the provision of a device of the character described which constitutes means for cigar holders, tobacco pipes, and cigars for filtering the smoke and also absorbing if desired the rank moisture which develops during the process of smoking a cigar or pipe, thereby trapping nicotin and preventing dust, small particles of tobacco or moisture from being drawn into the mouth or throat of the smoker.

Another object of the present invention is the provision of a device of the character described which constitutes a tasteless and odorless absorber of nicotin and the like that does not impair the taste of the tobacco smoke, and which in a cigar holder or pipe can be exchanged easily and quickly without the use of any tools as well as without the application of any considerable amount of skill.

A further object of'the present invention is the provision of a device of the character described which is concealed entirely within a cigar holder or a pipe, and at least to a large extent in a cigar, and which is of a small size and light in weight so that the outer appearance, size or weight of a smokers article provided with our new and improved filter arrangement will not be different to all extents and purposes from ordinary cigar holders, pipes or cigars without a filter. V

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangements of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing a preferred form of the invention has been shown.

In said drawing:

Figure 1 is a side view, fractionally in section, of a cigar holder provided with an embodiment of our invention;

Fig. 2 is an end view of the same;

Fig. 3 is a side view, fractionally in section, of a tobacco pipe provided with our filter arrangement;

Fig. 4 is a sectional view on the line 4--4 of Fig. 3;

Fig. 5 is a top view of a cigar provided with our new and improved filter arrangement;

Fig. 6 is a side view of the cigar of Fig. 5, fractionally in section;

Fig. 7 is a sectional view on the line 7-7 of Fig. 6;

Fig. 8 is a detailed enlarged side elevation, partially in section, of a tubular shell into which a portion of a roll of tobacco is extended;

Patented Dec. 6, 1960 F Fig. 9 is a. cross-sectional view on the line 9-9 of rig. 10 is a detailed, longitudinal sectional view of the tubular smell of Figs. 8 and 9;

Fig. 11 is a detailed longitudinal, fractional sectional view of the roll of tobacco of Figs. 8 and 9;

Fig. 12 is a detailed longitudinal, fractional sectional view of the roll of tobacco inserted into the shell of Figs. 8 and 9; and

Fig. 13 is a detailed longitudinal, fractional sectional view of the shell and the roll of tobacco of Figs. 8 and 9 and of a cover leaf.

Referring first to Figs. 1 and 2, the numeral 1 denotes a mouthpiece which has a taper portion 2 provided with a tubular extremity 3. A taper cigar holding shell 4 has an internal thread in its narrow portion 5, which is screwed upon an external thread on the tubular extremity 3. The shell 4 is adapted for receiving a cigar 7, and a filter 10 is removably inserted into the tubular extremity 3. The filter 10 may consist of any suitable filtering material, and it may be circular in cross-section as shown, or elliptical, or primarily fiat, or of any other form, shape and construction, the interior of the extremity 3 being shaped in cross-section in accordance with the cross-sectional shape of the filter 10. For exchanging a used filter 10 with a new one, the mouthpiece 1 is unscrewed from the threaded narrow portion 5 of the shell 4; thereupon the used filter 10 can be pulled outof the extremity 3 of the mouthpiece 1 easily and quickly, and a new filter can be inserted thereinto.

Referring now to Figs. 3 and 4, a mouthpiece 11 is secured to a stem 12 of a tobacco pipe 14, which has a bowl 15. Although the mouthpiece 11 could be screwed into the stem 12 in the same manner as in the embodiment of Figs. 1 and 2, the mouthpiece 1 is screwed into the narrow portion 5 of the shell 4, we prefer to attach the member 11 to the stem 12 in the manner shown in Figs. 3 and 4; there it will be seen that an intermediate tubular. bushing member 17 extends with one end into a widened end portion of the mouthpiece 11, and with its other end into a bore 20 of the stem 12, thus connecting the same to each other. A flange portion 21 preferably is outwardly extended from the member 17 intermediate its ends, and a filter 22 extends from a portion of the member 17 into the bore 20. The filter 22 here can be substantially of the same construction and design as the filter 10 of Figs. 1 and 2. Here also the filter 22 can be exchanged easily and quickly after the mouthpiece 11 has been pulled ofi the shaft 12, so that a portion of the filter 22 protruding beyond the member 17.can be pulled out of the same. The member 17 fits tightly into the parts 11 and 12, so as to afford a firm connection of the same when struck together.

In the embodiment of our invention of Figs. 5, 6, 7, 8. and 9 the principle of our invention is shown as used in connection with cigars, which are provided with simple, inexpensive smoke filtering mouthpieces that can be thrown away either partially, or entirely, when a smoker has consumed a cigar. Here a small, short mouthpiece 23 has a widened end portion 24, which preferably is provided with an internal thread, and a thin-walled tubular shell 25 has a reduced outwardly threaded end portion 27, which is screwed into the end portion 24 of the mouthpiece 23. The element 25 also has a thin-walled tubular holder portion 30, which is attached to, or formed as unit with, the end portion 27 of the shell 25. The holder portion 30 is wider and longer than the end portion 27, and is extended into an end portion of a cigar 31 in such a manner that the outer leaf 32 or the tobacco wrapping extends at least over the portion 30 of the shell 25, thus concealing the same. This is accomplished preferably by inserting the inner roll 43 of tobacco of the cigar 31 into the holder portion 30 during the process of manufacturing, and then rolling the cover leaf 32 over the inner tobacco as well as over the shell portion 30. The various steps of arranging the roll of tobacco 43 and the wrapper or cover leaf 32 are illustrated in Figs. to 13 inclusively. There, and in Figs. 6 and 8, it will be seen that first there is the shell 25 empty, and the roll of tobacco 43 has an end portion slightly compressed, so as to slide easily into the portion 30 of the shell 25 then the roll 43 is inserted into the element 25 (Fig. 12); and finally, the cover leaf 32 is wrapped around the main portion of the roll 43 as Well as the outer side of the hollow portion 30. Thus the member 25 is firmly united with the cigar, and can be pulled off the same only by exerting some force, so that an unwanted falling of the cigar out of the holder is impossible. A filter 33, which can be substantially of the same construction and design as the filter 10 of Figs. 1 and 2 or the filter 22 of Figs. 3 and 4, extends from the end portion 27 of the shell 25 into a widened bore portion '34 of the mouthpiece 23. As may be seen in Fig. 6, the axial bore extended through the mouthpiece 23 has three portions which are of different width. These three bore portions are, firstly the internally threaded Widest portion 40, secondly the intermediate portion 34, into which extends the filter 33 and which is of a lesser width than the portion 40, and thirdly the portion 41 which is still narrower than the portion 34 and which extends from the portion 34, or the filter 33, to the orifice of the mouth piece. Said portion 41 is intended as a passage for the smoke only. This construction allows an unscrewing of the mouthpiece 23 from the shell 25 when the cigar 31 has been consumed by a smoker, so that the shell 25 only will be thrown away with the cigar butt, while the mouthpiece 23, with a new filter 33 inserted thereinto, can be screwed upon the shell 25 of another cigar.

If the mouthpiece also is to be disposed of whenever a cigar has been smoked, the parts 23 and 25 can be made as a unit. In this case the filter arrangement and the design remain the same, only the screw connection of the portions 24 and 27 will be omitted, and the filter 33 has to be inserted prior to the rolling of the cigar into the holder portion 30.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described our said invention, what we claim as new and desire to secure by Letters Patent is:

1.
